Overwanking

Mostly used in the debating community. Overwanking means that you’re hyping up a fictional character by saying they are significantly stronger and more powerful than they actually are without much to back it up.

Example
Overwanker - Naruto & Sasuke can blow up Planets.

Normal Person - No they can’t, thats overwanking them.
